Carbon Dioxide - Dynamic and Kinematic Viscosity vs. Temperature and Pressure

Online calculator, figures and table showing dynamic and kinematic viscosity of carbon dioxide, CO2, at varying temperature and pressure - Imperial and SI Units.

The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress .

For further definitions, go to Absolute (dynamic) and kinematic viscosity . Absolute or dynamic viscosity is used to calculate Reynold's Number to determine if a fluid flow is laminar, transient or turbulent.

Tabulated values and viscosity units conversion are given below the figures.
